Krikri::PluginHelpers::IamUser

User-shaping logic for the amazon.aws.iam_user_info plugin - the same split the ec2_*_info modules use (thin plugin binary, logic in a PluginHelpers module spec-testable through the IamApi transport seam; see the plugin binary for the param semantics).

Field-path note: the IAM Query API's XML uses the request-style PascalCase names (UserName, Arn, CreateDate, UserId, Path, PasswordLastUsed) - NOT the snake_case keys the real module's result carries. boto3 parses GetUser/ListUsers into those snake_case dicts (its model maps UserName -> user_name etc. for the IAM namespace), so normalization reads the PascalCase wire element and emits the snake_case key.
